Above are folks in the longest line I've ever seen, waiting patiently in the wicked cold to get into Donald Trump's rally in Nashville today. The line went on for miles, and thousands of people - myself included - couldn't get in.

Tickets were free, and some local Resistance organizers were calling on folks to reserve tickets and not go, so there would be an embarrassing number of empty seats. That didn't happen. In Nashville, a blue city in the middle of a red state, Trump could probably have filled the arena twice.

Tennessee gave Trump 61 percent of its votes in November, but a poll last month had his approval rating down to 51 percent in the Volunteer State. All I can say from my experience today is that Trump's core supporters are definitely still behind him
